ABSTRACT

Objetivos: Comparar el crecimiento de Streptococus mutans antes y después de la aplicación de cetirizina y prednisona con y sin sacarosa a las 6, 12, 24 y 36 horas. Métodos: Diseño experimental, para ello se utilizó una muestra de 84 tubos de ensayo, 6 tubos por cada una de las medicinas o controles utilizados. Las variables que se consideraron fueron medicinas pediátricas con edulcorantes divididas en dos grupos: cetirizinas y prednisonas. En el grupo de las cetirizinas se consideraron las cetirizinas comerciales Hisaler®, Lergium® y Rigotax®, así como los preparados de cetirizina con xilitol, sacarosa y aspartame. En el grupo de las prednisonas se consideraron las prednisonas comerciales: Cortiprex® y Nisona® así como los preparados de prednisona con sacarosa y otros edulcorantes. La técnica que se empleó fue la de turbimetría la cual nos da el indicador absorvancia. Resultados: los resultados fueron leídos a las 6, 12, 24 y 36 horas. Conclusiones: Las medicinas comerciales que presentaron menor crecimiento de Streptococcus mutans fueron Rigotax® y Nisona®. Los preparados que presentaron menor crecimiento de Streptoccoccus mutans fueron cetirizina con aspartame y prednisona con edulcorante. Las medicinas comerciales presentaron diferencias estadísticamente significativas con sus respectivos preparados, produciéndose menor crecimiento de Streptococcus mutans en las medicinas comerciales.


Objetives: To compare the growth of Streptococcus mutans, before and after the application of cetirizine and prednisone with and without sucrose at 6, 12, 24 and 36 hours. Methods: The type of study was experimental. To carry it on, a sample of 84 test tubes was used, 6 tubes for each of the medications or controls. The variables considered were pediatric medication with sweeteners, divided in two groups: cetirizines and prednisones. In the cetirizines groups, those over the counter were: Hisaler®, Lergium® and Rigotax®; those that in their formulas included cetirizine with xylitol, sucrose, and aspartame. In the prednisone groups, which are over the counter, the following were found: Cortiprex® and Nisona®, as well as those that in their formulas included prednisone with saccarose and other sweeteners. The method used was turbimetry with the spectrophotometer, to meassure: absorbency. Results: The results were read at 6, 12, 24 and 36 hours. Conclusions: The commercial medications that showed less growth of the Streptococcus mutans, were Rigotax® and Nisona®. The preparation that showed less growth of the Streptococcus mutans were cetirizine with aspartame and prednisone with sorbitol. Over the counter medications showed significant statistical differences with their respective preparation, producing less growth of the Streptococcus mutans in over the counter medications.
